Hamworthy launches two new water heaters

Commercial boiler manufacturer and water heating expert Hamworthy Heating has extended its Dorchester range of direct fired water heaters.

The atmospheric low NOx Dorchester DR-LL water heater meets the requirements of ErP regulations and refurbishment projects alike: It can be used on old systems with existing flues (subject to survey), saving on costs for flue replacements. The integral stainless steel burner produces low NOx emissions (34-45 mg/kWh) and benefits from an automatic gas/air premix burning system for increased efficiency. The water heater is available as three models with continuous outputs (50°C delta T) of 850 to 1600 litres/hour, recovery rates from 12 to 23 minutes and a working pressure of up to 8 bar help to meet the continuous demands of bigger (taller) buildings.

The Dorchester DR-XP on the other hand is a condensing water heater with stainless steel tank available in two models (38-50kW input) of 184 litres. With an ErP efficiency of 91% – 93% and NOx emissions ≤ 53 mg/kWh, it is compliant with the latest ErP regulations that were further restricted in 2018.

Thanks to the grade 444 stainless steel tanks, no anodes are required to protect it from corrosion. This makes it a great choice for soft water areas. As fully room-sealed appliance, it can be sited in small compartmental areas. Flexible flue options mean the water heater can be installed almost anywhere.
